libpwstor is a library implementing a password storage format for C programmers. This format provides a reasonable level of security by utilizing SHA-256 in addition to a random salt to mitigate dictionary and rainbow table attacks. In addition to the core functionality, libpwstor also offers some additional functions such as Base64 encoding and decoding. All functionality is implemented and designed in such a way as to be easy to use for C programmers of varying skill levels, while preserving reasonable security in the underlying storage format.
userchroot is a small program which, in addition to doing a regular chroot, will also switch working directory once in chroot and drop privileges back to pre-suid values. It is intended to ease constructing chrooted user-driver services (running stfp-server in a restricted namespace for example). In order to conserve system resources, it is implemented in C. This makes it more suitable for higher load scenarios than scripts.
NeedSecure is program that makes it possible for system administrators and Web masters to protect member areas with passwords. It supports allowing and denying access to any protected directory for all members or for every member individually, recursive password protection, three levels of administration, extended member profiles with additional fields, limited and unlimited member accounts, language files and email templates that can be edited from an admin panel, optional activation codes, UTF-8 encoding support, statistics, and more.
NeedLock allows users to easily define directories that they want to protect and visitors who are allowed to view them. The script supports full member control, admin levels, statistics, account expiration, action logs, easy configuration, member registration setup, announcements, and many other unique features.
MatrixSSL is an embedded SSL and TLS implementation designed for small footprint devices and applications requiring low overhead per connection. The library is less than 50K on disk with cipher suites. It includes SSL and TLS client and server support, session resumption, and implementations of RSA, AES, 3DES, ARC4, SHA1, and MD5. The source is well documented and contains portability layers for additional operating systems, cipher suites, and cryptography providers.
